Single-storey, double-storey, rear and side extension drawings for Rottingdean homes — measured to Brighton & Hove City Council's design guidance, delivered in days and revised free until your decision, with a free approval-odds check before you commit.
Brighton & Hove City Council granted 89% of the householder planning decisions it made in its latest published year — 2 points above the 87% England-wide householder average. The flint-and-brick village core and green at Rottingdean are protected against alterations and materials that would erode the vernacular character, which is where a policy-literate drawing pack earns its keep. Its dominant interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. Rottingdean carries at least one Article 4 direction, and conservation areas including Rottingdean and Ovingdean remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Rottingdean is determined against an 8-week statutory target.
Rottingdean village (the flint High Street and green around St Margaret's church and the pond), Ovingdean (the smaller downland village around St Wulfran's church), Rottingdean seafront (clifftop houses along the undercliff and Marine Drive), Nevill estate (interwar and postwar semis climbing the western slope), Saltdean fringe (1930s seaside bungalows and semis toward the Lido) and Woodingdean edge (postwar downland-fringe housing above the village) — these are the Rottingdean pockets our drawings cover most. Heritage designations here include Rottingdean and Ovingdean. Brighton & Hove City Council weighs each proposal against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, where the northern edges of the village abut the South Downs National Park, where development on the open downland fringe is tightly restrained. Some of the larger village and seafront houses have been converted into flats, which carry no householder permitted-development rights.. On roofs the borough is pitched clay-tiled and slate roofs on the village houses and hipped roofs on the interwar semis and bungalows, over historic flint and brick village cottages, interwar and postwar seaside semis and bungalows and detached downland villas.
Rottingdean homes come in a handful of recurring shapes, and each one points to a different extension. The borough is built largely from historic flint and brick village cottages, interwar and postwar seaside semis and bungalows and detached downland villas, so a Victorian terrace usually wants a rear or side-return infill, while an interwar semi has room for a wider single-storey wrap or a two-storey side addition. Brighton & Hove City Council judges every one of them against Brighton & Hove City Plan (Parts One 2016 and Two 2022) and the relevant SPDs, weighing footprint, height and the impact on the house next door before it looks at the elevations.
That is why the drawings decide the outcome. We set the extension depth against the permitted-development limits precisely, keep the eaves and ridge within the allowances, and plot the 45-degree daylight lines to the neighbours' windows so the case officer can see the amenity test is passed. The flint-and-brick village core and green at Rottingdean are protected against alterations and materials that would erode the vernacular character, so we design around it from the first sketch rather than discover it at validation.
Rottingdean also protects whole streets — Rottingdean and Ovingdean among them. Rottingdean falls under the city-wide small-HMO Article 4 direction, and the Rottingdean conservation area — one of the historic downland villages designated in 1970 — adds Article 4 controls protecting its flint-and-brick village core. On designated land the larger-home extension route and most side extensions stop being permitted development, so we confirm your address against those layers before drawing a line.
Plenty of Rottingdean extensions are permitted development and need no planning application — a single-storey rear extension within the depth and height limits is the common case. You will normally need to apply to Brighton & Hove City Council if any of these apply:
We draw the footprint, the ridge and eaves heights and the neighbours' daylight on the page — the relationships Brighton & Hove City Council's officers weigh first — and submit a validation-complete pack, whether that is a lawful development certificate, a prior-approval notification or a full householder application.
Below is Brighton & Hove City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Brighton & Hove approves most householder work, and in Rottingdean the deciding factors are the protected village character and the sensitive downland and coastal setting rather than the principle of extending. A complete, policy-literate extension pack anticipates those pressure points before submission, which is why professionally drawn applications are decided faster and refused less often than DIY ones.

Across Rottingdean village, Ovingdean and Rottingdean seafront, the extension that lands most often is the single-storey rear addition — a glazed kitchen-diner across the back of the house, kept within the permitted-development depth or taken to a full application where the ground floor wants more. On the borough's historic flint and brick village cottages, a side-return infill frequently pairs with it to square off the plan; on wider detached downland villas, a two-storey side or rear extension can add a bedroom above without swallowing the garden.
The northern edges of the village abut the South Downs National Park, where development on the open downland fringe is tightly restrained. We size the extension to the amenity and daylight tests, match the roof and materials to the host house, and keep enough garden to satisfy Brighton & Hove City Council's space standards — so the scheme answers the borough's questions before an objection can raise them. Where permitted-development rights are used up or removed, we prepare the householder application to the council's extension design guidance instead.
We draw extensions on every street in the borough. A few of the neighbourhoods where Rottingdean projects come up most often:

The right extension in Rottingdean depends on your house type and how much garden you can give up. This is how the main options compare on planning route and what they add.
| Extension type | Permitted development? | What it adds | What Brighton & Hove City Council checks |
|---|---|---|---|
| Single-storey rear | Often, within 3m/4m depth (6m/8m via prior approval) | Bigger kitchen-diner across the back | Depth, height, neighbour daylight (45°) |
| Side-return infill | Sometimes, if within width and height limits | Squares off an L-shaped ground floor | Width vs the original house, glazing to boundary |
| Two-storey rear/side | No — full application | Extra bedroom or bathroom above | Bulk, overlooking, 7m rear-boundary gap |
| Wraparound (rear + side) | No — full application | Whole-width open-plan ground floor | Combined footprint and garden retained |
Route depends on your street — conservation areas such as Rottingdean and Ovingdean and Article 4 directions can remove permitted-development rights.
A fixed process built around how Brighton & Hove City Council validates and decides householder extension applications — most drawings are submission-ready within seven days of survey.
Tell us your Rottingdean postcode and house type. We confirm your conservation and Article 4 status, how much permitted-development depth you have left, and score your odds against live Brighton & Hove City Council decisions.
We measure the existing footprint, floor and eaves levels, boundary distances and the neighbours' window positions — the numbers the depth limits and daylight tests depend on.
Chartered designers develop the single-storey, two-storey or side extension to your brief, drawn inside the permitted-development limits or to Brighton & Hove City Council's extension design guidance.
We submit the certificate, prior-approval notice or application, manage validation and case-officer queries, and revise the drawings free until Brighton & Hove City Council issues its decision.
Not always. A single-storey rear extension up to 3 metres deep on a terrace or semi, or 4 metres on a detached house, and no higher than 4 metres, is usually permitted development. In Rottingdean you will need to apply to Brighton & Hove City Council for two-storey extensions, side extensions wider than half the house, anything forward of the front wall, deeper rear extensions under the larger-home prior-approval route, and any extension in a conservation area such as Rottingdean and Ovingdean.
Standard permitted development allows 3 metres on a terraced or semi-detached house and 4 metres on a detached one. The larger-home extension scheme can double that to 6 or 8 metres, but it needs a prior-approval notification to Brighton & Hove City Council and a neighbour-consultation period, and it does not apply on designated land such as Rottingdean's conservation areas. We confirm which route your property qualifies for before drawing.
Two-storey and double-storey extensions almost always need a full householder application to Brighton & Hove City Council, because they fall outside permitted development on most homes. The council looks closely at bulk, overlooking of neighbours and the 7-metre gap a two-storey rear extension must keep from the rear boundary. We design to those tests and show the daylight and privacy angles on the drawings. This applies to your Rottingdean address specifically.
A householder planning application in Rottingdean runs to a statutory eight-week target, a larger-home prior-approval notification to around six weeks including the neighbour-consultation period, and a lawful development certificate to eight weeks. Incomplete submissions stall at validation, so we submit a complete pack and manage officer queries to keep the decision on schedule. Brighton & Hove City Council is the decision-maker.
Yes — planning permission and building regulations are separate consents, and almost every extension needs both. Planning governs whether you can build it; building control governs how it is built, covering structure, insulation, drainage and fire safety. We prepare the building-regulations drawings alongside the planning set so Brighton & Hove City Council's building control or an approved inspector can sign the work off. This applies to your Rottingdean address specifically.
Every house and brief is different, so we price each Rottingdean extension individually and send a fixed, no-obligation quote back within one working day. It covers the full drawing pack with free revisions until Brighton & Hove City Council approves, and we tell you upfront whether your extension qualifies as permitted development.
